SEWER-PIPE.

Specification of Letters Patent. I

Patented July 1 '7, 1 906.

To*v all whom it may concern..-

Be it known that we, GEORGE FELTZ and WILLIAM S. EAST, citizens of the United States, and residents of Lima, in the county of Allen and State of Ohio, have invented a new and Improved Sewer-Pi e, of which the following is a full, clear, and) exact description. L

This invention relates to pipes, such as used inthe construction of sewers andculverts.

The objectof the invention is to produce a pipe of this kind Which is simple in construction and arranged so that the succeeding sections interlock with each other.

Further obj ects of the invention are to preyent scouring under the pipe and to provide inproved means for attaching the pipe to a khead, such as found especially in culvert construction.

The invention consists in the construction and combination of parts to be more fully described hereinafter, and definitely setforth in the claims.

- Reference is to'be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding arts in all the figures.

Figure 1 is a side e evationshowing two connected sections of the pipe and illustrating one of said sections attached to a bulkhead. Fig. 2 is a plan showing the interior of the lower ortion ofthe pipe as represented in Fig. 1, t e upper portion of the ipe being represented simply as removed. Fig. 3 isa cross-section on the line 3 3 of Fig. l. Fig. 4 vis a reverse plan showing one extremity of the upper' side of a pipe-section; and Fig. 5 is `a fragmentary view snowing a portion of the wall of a pipe-section and illustrating especially the form of certain lugs, which constitute a feature of the invention.

Referring more particularly to the parts, 1 and 2 reprosont'two connected pipe-sections. The pipe-Section 1 represents the usual form of the pipe, while the pipe-section 2 re iresents a modified construction ailopted where a connection is to be made with a flange or bulkhead 3. 'lliese )ipc-sections l and 2 are themselves formed in two sections -l and 5, the lower sections being substantially flat below and having diverging upwardly-cxtending sido walls (i. The upper sections 5 constitute domes or caps vfor the lower sec- 5 5 tions. The edges of these u per and lower sections come together, as indicated in Fig. 3,

and in order to improve the connection we prefer to form one of the edges at'each joint with a channel 7, which receives the opposite edge, as shown. The adjacent extremities of the pipe-sections are formed so as to produce an interlocking -joint 8, as indicated most clearly in Fig. 2. For this purpose one of the sections, such as the section 2, isrovided with a bead or rounded flange 9, anc the opposite pipe-section is formed with a groove 10, receiving the aforesaid bead 9, as will be readily understood. By this arrangement the successive sectionsA of -the pipe may be jointed together, and, furthermore, each ipesection is itself composed of two jointe sections meeting in a horizontal line.

The pipe-sections 1 and '2 are further provided vwith circumferential ribs 11, the Vpurppse of which will appear more fully hereina ter.

When attachment is to be made to a flan e or bulkhead 3, We prefer to form the bul head 3 in two sections 3 and 3b, and these sec- 8o tions are divided on a horizontal line 12, which corresponds substantially with the-horizontal meeting edges of the upper and lower sections of the pipe, as indicated most clearly in Fig.

3. These bulkhead-sections 3a and 3b are 2S# adapted to be connected directly together, for which purpose We provide op ositely-dis-l posed lugsgl, through which bo ts or rivets 14 pass, as indicated. At'suitable points on the outer face of the wall of the pipe-section 2, to which the bulkhead is to be attached, we provide-a plurality of lugs 15, the form of which is very clearl illustrated in Fig. 5. These lugs are simply knobs or projections having T-slots 16 cut centrally therein and 95 rei-rive trai'isvcrse pins 20. lt should be un- IOO derstood that in attaching the pipe-section to the bulkhead these arms 17 are received in the T-,slots 16, the Webs 19 thereof passing through. the contracted part of the slots, as will be readily understood, the iianges 18 be- `ing received in the enlarged portions of the slots. After the pipe is attached to the bulkhead the transverse pins 20 are driven in, and the openings of these pins are so located that the pins rest against the sides of the lugs 15 remote rom the bulkhead. In this way the pins operate to hold the bulkhead rigidly to 'the pipesection.

The langes having the grooves 10\of the pipe-sections project outwardly from the body oi: the pipe, as illustrated most clearly in Fig. 2, and these have a tendency to prevent scouring out of the dirt or similar material under the, pipe-line. The ribs 11 referred to above have the same general purpose and also tend to prevent the dislodgment of the pipe after being laid. While we prefer to give the grooves 7 the form referred to, these grooves may have any form desired. By forming the pipe-sections with substantially flat bottoms a better support is formed for the same, which tends to prevent sinking of the pipe after being laid, and, furthermore, this form of pipe is conducive to a high eiiiciency in How of the current within tne same.

With the bulkhead attachment described a liberal amount of expansion and contraction may take place in the pipe-line without ma terially displacing the bulkhead. This occurs, of course, because there is necessarily a certain amount of play or lost motion at the pins 20.

Having thus described our invention, We

claim as new and desire to secure by Letters 4o Patent- 1. A pipe-section having lugs on the outer face thereof, said lugs havin slots formed therethrough, and a bulkhea abutting the extremity of said ipe and having arms pass- 45 'ing through said s ots, and means for retaining said arms in said slots.

2. A pipe-section comprising an upper section and a lower sectionl Jomted thereto, said pipe-sections having lugs formedA on the outer 5c side thereof with transverse slots and-a bulkhead abutting the extremity of sa'idpi e-section and having arms passing throng said slots and pins passing through said arms and engaging said lugs.

3. A pipe-section comprising an upper section and a lower section jointed thereto, -a bulkhead formed in sections corresponding to said upper and lower sections and abutting the extremity of said pipe-section, said pipe- '6o section having lugs on the outer side thereof with T-slots therethrough said bulkhead having arms on the inner face thereof projecting through said slots and lying against the outer face of -said pipe-section, and pins 65 passing through said arms and engagin vthe remote sid'es of said lugs to retain said ulkhead.

In testimony whereof we have signed our names-to this specification in the' presence .of 7o
